For more money/shorter commute?

Here's my situation: I'm currently on maternity leave from my job - I love it, love my manager and my coworkers, all who will be a good support system to me when I return to work. The only downside is it's ~40 minute commute each way. I recently interviewed for a position at a facility 5 minutes from my house and would be asking for ~$8,000 more per year. There is also a daycare on site (but they don't currently have any openings).

I know it seems like a no brainer, but I'm so comfortable in my current position. What would you do?
